What evidence do the positions of the peaks and dips in its spectrum provide about an object? A. expansion B. elemental composition C. motion D. temperature​

Answers

Given what we know about the use of spectrums, we can confirm that the positions of peaks and dips provide information as to the elemental composition of the object in question.

The question asks about the dips and peaks of a spectrum, which allows us to assume we are dealing with Infrared spectroscopy and IR spectrums. This is defined as the measurement of how certain matter interacts with infrared radiation.

These graphs are used to measure how this matter absorbs, reflects, or even emits said radiation. Therefore, the use of spectrums allows us to infer as to the chemicals present or functional groups of an object, and therefore its elemental composition.

When looking at the spectrum graph, we will see that at times the curve dips down, which indicates that less light is transmitted. That means light is being absorbed. Due to the fact that bonds absorb different frequencies of light, the peaks tell you what kinds of bonds are present from which we can identify the elemental composition.

What is the empirical formula of a compound that contains 4.03 g of hydrogen per mole, 64.14 g of sulfur per mole, and 128.00 g of oxygen per mole?

Answers

Answer:

Oct 27, 2015 · CH_4 For this kind of problem, you can assume that the weight of the unknown sample is 100g ( since 75% C + 25% H = 100%). Thus, weight of C = 75g weight of H = 25g Since chemical formulas deal with number of moles rather than weight in grams, you need to convert each element by multiplying it to their respective atomic masses.

Explanation:

The empirical formular i H₂SO₄

The first step is to calculate the compound by the molar mass

Hydrogen,   Sulphur,   Oxygen

4.03/1   ,   64.14/32   ,   128/16

4.03  , 2  ,   8

Divide by the lowest value

Fill in the blanks correctly

Answers

Answer:

Explanation:

A base pair is two chemical bases bonded to one another forming a "rung of the DNA ladder." The DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups. Attached to each sugar is one of four bases--adenine (A), cytosine (C), guanine (G), or thymine (T). The two strands are held together by hydrogen bonds between the bases, with adenine forming a base pair with thymine, and cytosine forming a base pair with guanine.

Describe how gravity is associated with many erosional agents.

Answers

Answer:

Gravity is associated with many erosional agents, because the force of gravity tends to pull all material down the slope. is when a rill channel evolves to become deep and wide. glaciers are dense so they can carry large rocks and debris for a long distance.

Role of gravity in erosion, because gravity tries to draw everything down the slope, gravity is linked to numerous erosional agents.

What are erosional agents?

Glaciers and running water both erode due to gravity. This is a result of gravity pulling water and ice downward. These are examples of indirect effects of gravity on erosion.

Due to the force of gravity, mass movement is an erosional process that carries rocks and sediments down slope. The material is moved from higher heights to lower elevations, where it can be picked up and moved to even lower levels by other carrying mechanisms like streams or glaciers.

Therefore, glaciers and running water both erode due to gravity. This is a result of gravity pulling water and ice downward. These are examples of indirect effects of gravity on erosion.

This model chose to include certain features and exclude other features. For example, this simulation only includes rabbits, wolves, and grass but there are other predators of rabbits and other food sources for rabbits. Why do you think the creators focused on these data elements and not others

Answers

The creator focused on these data elements and not others because he was trying to create a food chain instead of a food web.

In the ecosystem, the living and non-living things interact over time leading to exchange of energy.

A food chain can be defined as the steps through which energy transfer occurs in an ecosystem.

The energy flows from the producers (grass), primary consumers, (rabbits) and then the secondary consumers (wolves).

The energy flow is indicated with an arrow thus,

grass ---> rabbit -----> wolves.

Food chain, therefore includes linear sequence of organisms.

Food web on the other hand illustrates a complex feeding relationship within the ecosystem.

The food web is made up of a prey that can be eaten by more than one predator.

Therefore, even though there where other predators of rabbits and other food sources for rabbits, he chose only few features to create a food chain.
